If at first, you don’t succeed in showing that widespread voter fraud will happen in the 2020 presidential election, try, try again.

The Washington Post says that the campaign hired a second opinion after researchers at a business paid for by former President Donald Trump’s campaign found no proof to back up the fraud claims. In an interview with the Post, Ken Block, the founder of the second company, Simpatico Software Systems, said, “No real voter fraud was found in my investigations, and I couldn’t back up any of the outside claims of voter fraud that I was asked to look into.” He also said, “Every fraud claim I was asked to look into was not true.”

Block’s company was paid more than $750,000 in six packages marked “Recount.” The first payment came three days after the election. Block told the newspaper that he had recently gotten a subpoena from Jack Smith, the special counsel who is looking into whether classified documents were mishandled at Trump’s Mar-a-Lago resort, but he wouldn’t say anything else about the case.
